skimcoat with drywall compound if it's a lot of damage, for little stuff just smooth and spackle. Use a wide knife (10-12) don't put on too much, do 1 or 2 coats as needed.
I usually prime the damaged areas before mudding because i've heard if you don't you can get bubbles in the mud or something. Maybe its not necessary but I do it, just quickly with a spraycan.
